nance so that the audio plays at a more comfortable level. Although it is usually set to a level lower than the
‘Main Volume Level’, it can be set anywhere, including higher values.
If the Sd-50/xx has been set to use RealTime Level Controls from DMX-512 , MIDI in , or Show Control
data, then the ‘half mute’ level is scaled from whatever level these RealTime controls are setting as the ‘full
volume’ levels.
3) RealTime Level Control
When enabled, Audio Levels can be controlled from:
1)
DMX-512 data received through the DMX-512/MIDI serial port (if DMX-512 reception is enabled).
2)
RealTime Serial data received through the RS-232 serial port.
3)
RealTime Serial data received through the DMX-512/MIDI serial port (if Net Serial is enabled).
4)
MIDI data received through the DMX-512/MIDI serial port (if MIDI in is enabled, and ‘MIDI notes
trigger animation playback’ is NOT selected).
In the first three cases above, the ‘level Control Channels’ set where the data for controlling the left and
right outputs comes from. These can be set to different addresses, or the same address if you want a sin-
gle analog channel to control both left and right outputs.
To control output levels when triggering SoundFiles from MIDI in , the ‘Note On’ velocity is used. Note
velocity values from 1 though 127 translate into audio levels 0-100%. If a SoundFile is started with a high
‘Note On’ velocity, it will play loudly. If it is started with a low velocity, it will play more softly.
4) EQ Settings
You should always try to adjust your EQ before recording your SoundFiles. This equalizer is used to
make up for sins in the studio by allowing you to adjust the overall EQ of the Sd-50/xx.
5) Enable Power Amplifier
This is used to turn on and off the onboard power amplifier.
If you are not using the power amplifier, you should turn it off. The Sd-50/xx will run much cooler if the
amplifier is turned off.
If you are using the onboard amplifier, you won’t hear much coming out of it until you turn it ON.
To save power and reduce heating, the amplifier is turned off any time the Sd-50/xx is not playing a
sound.
